近年来在克山病非生物病因研究中,营养和缺血与克山病发病的关系是引人注目的两个問題。应用实验病理学方法探討克山病病因,国內共它省区已有报道,但在甘肃省尚未开展。对于实驗結果的观察,目前大多是采用普通光鏡,而超微結构的研究資料尚很缺乏。为此我們采用甘肃省克山病病区粮飼养大鼠,通过对三个不同飼料組大鼠心肌的光 In recent years, Keshan disease in non-biological etiology, nutrition and ischemia and Keshan disease incidence is striking two issues. Experimental pathology method to explore the etiology of Keshan disease, the province has been reported in other provinces, but not yet in Gansu Province. For the observation of the experimental results, most of the current ordinary light microscopy, and the ultrastructure of the research data is still lacking. To this end, we used Keshan disease in Gansu Province, food-fed rats, through the three different feed groups of rat myocardial light
